“…The ongoing crisis offers a chance to address inequity with a focus on residential energy burdens 49 . The EU is in the process of defining how communities can participate in the energy transition 50 and how burdens can be alleviated through this process using proactive policy tools and business models such as One Stop Shops (OSS) for energy efficiency and renewable energy upgrades 51 . Adopting energy criteria for energy and other programs like these could expand access for those underserved populations in need of assistance independent of their needs in other consumption categories.…”

Energy inequity is an issue of increasing urgency. Few policy-relevant datasets evaluate the energy burden of typical American households. Here, we develop a framework using Net Energy Analysis and household socioeconomic data to measure systematic energy inequity among critical groups that need policy attention. We find substantial instances of energy poverty in the United States – 16% of households experience energy poverty as presently defined as spending more than 6% of household income on energy expenditures. More than 5.2 million households above the Federal Poverty Line face energy poverty, disproportionately burdening Black, Hispanic, and Native American communities. For solar, wind, and energy efficiency to address socioeconomic mobility, programs must reduce energy expenditures by expanding eligibility requirements for support and access to improved conservation measures, efficiency upgrades, and distributed renewables. We recommend the United States develop a more inclusive federal energy poverty categorization that increases assistance for household energy costs.

“…Currently, little is known about how to improve these appliances for better energy efficiency and cost-effectiveness management. It has been observed by numerous electrical engineering experts, like [45] and two of the experts in this study, that the sizes of the existing electrical appliances that have been currently installed in condominiums in cities like Bangkok, are too large for the levels of energy usage and, as a result, the operation of the appliances appears to be significantly lower than their optimal capacity. It is estimated that downsizing the currently installed and used electrical appliances can help condominiums achieve energy efficiency and cost effectiveness management.…”

“…Condominium annual cooling energy demands can be reduced when important design variables that can be decided at an early stage for energy efficient design are taken into account. Similarly, numerous studies [39][40][41][42][43][44][45][46] examined the systems for energy efficiency. For instance, one study [47] built a model to estimate the final energy intensity of the building sector for space heating, household hot water, electricity for space cooling, and electricity for spaceless cooling in New York City, this model assumed that the final use depends largely on the functionality of the building, not on the type of construction or age of the building.…”

A direct use approach incorporating a cost approach assumed that replacing oversized electrical appliances with those better fit to actual energy consumption can reduce energy consumption, optimizing capacities of the new appliances to the maximum while reducing electricity costs. This study aimed to verify the assumption that the size of appliances has impacts on energy consumption and cost effectiveness. A mixed-method approach included these instruments for data elicitations (i.e., a questionnaire, data records of 485 transformers, two assessments of condominium technical caretakers, and two in-depth interviews of electrical engineering experts). The findings revealed that most condominiums installed electric appliances that are too large for their actual energy usage, which lies between 5.4% and 7.1% of the capacity. This study therefore proposed a total cost reduction of 54% by downsizing these appliances (i.e., MV Switchgear 2 sets, dry type transformer 2 sets 80,000, LV Cable 10 m. (XLPE), main distribution board, Busduct (MDB-DB), generator (20% of Tr.), and generator installation). Even though this analysis is limited to Bangkok, Thailand, this case may contribute decision-making on electrical appliance selection at early stage of investment or to downsize the currently installed appliances for the more energy efficient and cost-effective management of condominiums around the world.

“…There are many barriers faced by the sector, from technical barriers to regulatory and market risks [19]. According to Bertoldi et al [20] one reason behind such a partial inefficacy might be related to the fact that informational measures aimed at encouraging renovation are poorly explained and understood. Moreover, renovation decisions are also influenced by personal (such as age) and other contextual factors related to everyday life [21].…”

“…The European Commission has recently launched a new specific strategy to promote renovations of buildings-A Renovation Wave for Europe-Greening our buildings, creating jobs, improving lives [19]. As part of the Renovation Wave strategy, the European Commission has strengthened its commitment to tackle energy poverty, in which renovation is acknowledged as a key strategy to address energy poverty [20]. Energy efficiency of buildings, particularly of the housing segment, is one of the flagship areas-RENOVATE-of the EU Recovery and Resilience Facility under the NextGenerationEU instrument [22].…”

A Staged Approach for Energy Retrofitting an Old Service Building: A Cost-Optimal Assessment

Office buildings built before the pre-1960 age constitute a relevant group for analyzing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. By using a staged renovation approach, two passive technologies applied to the building envelope and an efficient domestic hot water system were selected and a financial evaluation through the net saving (NS) method was undertaken to choose the best efficiency measures/packages for improving the building’s energy performance. Real discount rates of 3% and 1% were used in the financial evaluation. Considering the real discount rate of 3%, the results showed that only two out seven retrofit options had a positive financial return. By using the real discount rate of 1%, all retrofit options were found to be financially efficient. The results of the study corroborated those of earlier works that found that the financial profitability of energy renovation investments is very sensitive to the discount rate used in the analysis. The results of the study also suggested that the staged renovation approach used in the analysis is economically feasible, and that this approach is an alternative to one-step renovation approach to help to achieve the country´s energy and climate targets by 2030. Suggestions for future research conducted for office buildings in the different climate zones and other age groups in Portugal are proposed.
